The Fourth of July fireworks and festivities are spread over several days in New Jersey in 2025. See our town-by-town listing.

These fireworks can be purchased by a person 18 or older between June 4 and July 4 and between Dec. 1 and Jan 1. Although there are monthlong purchase periods, the Delaware Office of the State Fire Marshal stressed that permitted types of fireworks may be used only on July 4, Dec. 31 and Jan 1.

With nearly all of the aerial shells, paper rockets and sparkly fountains that fuel America’s Fourth of July celebrations being imported from China, volunteer groups like Johnson’s and cities big and small have been closely watching the negotiations.
